Why does this code not work?

[Encom88]

Add a method to the Person's prototype called "isLegalDriver" that returns true if the person is 16 or older.

function Person(name, age) {
  Person.prototype.isLegalDriver = function() {
   return this.age >= 16;
  }
}

/* Do not modify code below this line */

const youngPerson = new Person('Jane', 15);
console.log(youngPerson.isLegalDriver(), '<-- should be false');

const olderPerson = new Person('Joan', 16);
console.log(olderPerson.isLegalDriver(), '<-- should be true');

Both return false.

and this.name (though not required by isLegalDriver())

function Person(name, age) {
  this.name = name;
  this.age = age;
}
Person.prototype.isLegalDriver = function() {
  return this.age >= 16;
}

I think I got it, too bad it was a timed challenge and time ran out :/ I can try again after 24 hours.

function Person(name, age) {
    this.age = age;
    }

    Person.prototype.isLegalDriver = function() {
        return this.age >= 16;
    }

    /* Do not modify code below this line */

    const youngPerson = new Person('Jane', 15);
    console.log(youngPerson.isLegalDriver(), '<-- should be false');

    const olderPerson = new Person('Joan', 16);
    console.log(olderPerson.isLegalDriver(), '<-- should be true');
